STOPPER FOR BOTTLES.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed April 19, 1905. Serial No. 256,351.

, following is a specification.

My invention relates to non-refillable bottles, and has for its objects to produce a comparatively simple and inexpensive bottle of this character which after being filled and sealed will permit free discharge of its contents, but prevent the introduction of liquid into the bottle, thereby obviating the fraudulent substitution of an inferior grade of goods for that originally contained in the bottle.

A further object of the invention is to pro vide a device of this character which will insure free entrance of air to create pressure in the bottle during canting of the latter.

To these ends the invention comprises the novel features of construction and combination of parts, as will be hereinafter more fully described.

In the accompanying drawings, Figure 1 is avertical section through the neck of a bottle embodying my invention. Fig. 2 is a reverse plan view of the valve-retaining member or disk. Fig. 3 is a perspective view of one of the valves. Fig. 4 is a view similar to Fig. 1, showing a modified embodiment of the invention.

Referring to the drawings, 1 designates a bottle-neck, in which is seated a body or closure 2, provided with a discharge-opening 3, having a valve-seat 4, and an air-inlet opening 6, having a valve-seat 7, said body being fixed in the neck in any appropriate manner, but preferably by means of a cement filling 8, within a chamber formed by registering marginal recesses in the body and neck.

Movably disposed in the discharge opening or passage 3, which is provided above the seat 4 with longitudinal grooves 3, is a main valve 9, shouldered at 10 to form a head which fits upon the seat 4, while within the opening or passage 6 there is arranged an auxiliary movable valve 11, likewise shouldered, as at 12, to present a head which fits upon the seat 7, there being arranged above said valves a disk-like guard or shield 13, seated in a suitable socket formed for its reception in the normally upper end of the body 2. The shield 13 has an opening or perforation 14 disposed above the valve 9 and a second opening or perforation 15 above the valve 11, it being noted that the inner face of the shield is concaved throughout a portion of its surface surrounding the respective openings, whereby the liquid will flow properly to and through the latter, while formed in the upper face of valve 9 are suitable radial grooves or recesses 9, which cooperate with the concaved face of the shield 13 to insure free passage of the liquid, there being formed for a similar purpose in the body of the valve and for cooperation with the grooves 3 a plurality of longitudinal grooves 10.

In practice, after the bottle has been filled,

the bodyv 2-is seated and securedwithin the neck, the valves having been previously positioned in the body and the guard applied and cemented in place. When the bottle is canted during the operation of discharging the liquid therefrom, the valves 9 and 11 will open togpermit the liquid to flow freely through the passage 3 and air to enter through the passage 6, it' being apparent that under this arrangement the necessary air-pressure will be maintained in the bottle to insure free discharge of its contents. It is to be observed that except when discharging the liquid the valves will remain seated, thus preventing the introduction of liquid into the bottle and obviating the fraudulent substitution of an inferior grade of goods for that originally contained in the bottle. Further, it will. be noted that the openings 14 and 15 are of such relative sizes as to insure free passage of the liquid through opening 14 and the supply of a requisite quantity of air through the opening 15, the valves 9 and 11, which are completely housed within the body 2, being of proper relative size to accord with the respective openings 14 and 15.

In Fig. 4 I have illustrated a modified form of the device in which the body 2 is secured in the neck 1 by means of a split spring-ring 16-and is provided with a single dischargepassage 3, in which is movably disposed a valve 9, there being secured within arecess in the upper end of the body a guard or shield 13-, having openings 14 and 15. In this form of the device when the bottle is canted and the valve moves to open position the liquid will flow outwardly through the opening 14, and the air tomaintain pressure in the bottle will enter through the opening 15. In other respects the construction and operation is practically identical with that above described.

From the foregoing it is apparent that I produce a simple and inexpensive-device admirably adapted for the attainment of the ends in view, it being understood that minor changes hereinafter set forth may be resorted to without departing from the spirit and scope of the invention.

Having thus described my invention, What I claim is- 1. A bottle and its neck, a body seated in the latter and provided with a discharge and an inlet passage, said passages being of relatively different sizes and having valve-seats, valves movably disposed in the passages to close on said seats and housed wholly within the body, the latter having its normally upper end recessed, and a shield seated and secured in said recess and provided with a discharge and an inlet opening of relatively different sizes and adapted to communicate With the respective passages, the inner face of the shield being concaved at points surrounding the openings.

2. A bottle and its neck, a body seated in the latter and provided with a discharge-passage having a valve-seat, a valve movably disposed in the passage to close on said seat and housed Wholly Within the body, said valve having its outer end face provided Wit-h radial recesses and its side Wall grooved longitudinally and a shield fixed at the outer end of the body above the said valve and provided with a discharge-opening and an air inlet opening, said openings being of relatively diflerent sizes and the inner face of the shield concaved throughout a portion of its area around said openings.

In testimony whereofI aflixmy signature in presence of two Witnesses.

GEORGE STANICH.
